On top of the benefits of the above introduced scalabilities, there are several other advantages
furnished by H.264/SVC. One of such remarkable features of H.264/SVC is the support
for video bit rate adaptation at NAL (Network Application Layer) packet level, which
significantly increases the flexibility of the video encoder. Alternative scalable solutions,
however, only support adaptation at the level of slices or entire frames (Huang et al., 2007).
Furthermore, H.264/SVC improves the compression efficiency by incorporating an enhanced
and innovative mechanism for inter-layer estimation, called ILP (Inter-Layer Prediction). ILP
reuses inter-layer motion vectors, intra texture and residue information among subsequent
layers (Husemann et al., 2009).
